Truk is a wreck divers paradise! The island's lagoon provided the Japanese with a deep and safe anchorage for freighters, tankers and supply ships, a vital logistic and strategic staging post during World War II as the Japanese Fleet swept all before it on its seemingly invincible march across the Pacific. By 1944, as Japan was in retreat across all fronts, Truk would often contain dozens of warships and supply ships. On 17-18 February 1944, during Operation Hailstorm, the US Fleet launched a massive air attack on the Japanese Fleet lying in Truk Lagoon. Over 60 ships now rest on the sea floor, encrusted in a wealth of corals and sponges and shrouded in colourful clouds of fish. Some of the wrecks are too deep from conventional scuba diving but the majority are accessible to divers of all experiences.

The Blue Lagoon Resort provides a convenient base for those looking for occasional diving, while the liveaboards Truk Odyssey and Truk Aggressor operate extended charters to Truk's legendary "Ghost Fleet" and to some of her fantastic outer reefs.
